■Engine oil consumption●The amount of engine oil consumed depends on the oil viscosity, the
quality of the oil and the way the vehicle is driven.
●More oil is consumed under driving conditions such as high speeds andfrequent acceleration and deceleration.
●A new engine consumes more oil.
●When judging the amount of oil consumption, keep in mind that the oilmay have become diluted, making it difficult to judge the true level accu-rately.
●Oil consumption: Max. 1.1 qt./600 miles (0.9 Imp. qt./600 miles, 1.0 L/1000 km)
● If your vehicle consumes more than 1.1 qt. (1.0 L, 0.9 Imp. qt.) every 600miles (1000 km), contact your Toyota dealer.
CAUTION
■Used engine oil●Used engine oil contains potentially harmful contaminants which may
cause skin disorders such as inflammation or skin cancer, so care shouldbe taken to avoid prolonged and repeated contact. To remove used engineoil from your skin, wash thoroughly with soap and water.
●Dispose of used oil and filters only in a safe and acceptable manner. Donot dispose of used oil and filters in household trash, in sewers or onto theground. Call your Toyota dealer, service station or auto parts store forinformation concerning recycling or disposal.
●Do not leave used engine oil within the reach of children.

4-3. Do-it-yourself maintenance
Installing tire pressure warning valves and transmitters
When replacing tires or wheels, tire pressure warning valves andtransmitters must also be installed.
When new tire pressure warning valves and transmitters areinstalled, new ID codes must be registered in the tire pressure warn-ing computer and the tire pressure warning system must be initial-ized. Have tire pressure warning valve and transmitter ID codesregistered by your Toyota dealer. (→P. 369)
■ The tire pressure warning system must be initialized in the fol-lowing circumstances:● When the tire inflation pressure is changed such as when
changing travelling speed or load weight
● When changing the tire size
When the tire pressure warning system is initialized, the current tireinflation pressure is set as the benchmark pressure.
■ How to initialize the tire pressure warning systemPark the vehicle in a safe place and turn the engine switch(vehicles without a smart key system) or the “ENGINE STARTSTOP” switch (vehicles with a smart key system) off.Initialization cannot be performed while the vehicle is moving.
Adjust the tire inflation pressure to the specified cold tire infla-tion pressure level. (→P. 474)Make sure to adjust the tire pressure to the specified cold tireinflation pressure level. The tire pressure warning system willoperate based on this pressure level.
Turn the engine switch to the “ON” position (vehicles without asmart key system) or “ENGINE START STOP” switch to IGNI-TION ON mode (vehicles with a smart key system).

■When to replace your vehicle’s tiresTires should be replaced if:●You have tire damage such as cuts, splits, cracks deep enough to
expose the fabric, and bulges indicating internal damage●A tire goes flat repeatedly or cannot be properly repaired due to the
size or location of a cut or other damageIf you are not sure, consult with your Toyota dealer.
■Replacing tires and wheels If the ID code of the tire pressure warning valve and transmitter is notregistered, the tire pressure warning system will not work properly. Afterdriving for about 20 minutes, the tire pressure warning light blinks for 1minute and stays on to indicate a system malfunction.
■Tire lifeAny tire over 6 years old must be checked by a qualified technician evenif it has seldom or never been used or damage is not obvious.
■Routine tire inflation pressure checks The tire pressure warning system does not replace routine tire inflationpressure checks. Make sure to check tire inflation pressure as part ofyour routine of daily vehicle checks.
■Low profile tires (vehicles with 18-inch tires) Generally, low profile tires will wear more rapidly and tire grip perfor-mance will be reduced on snowy and/or icy roads when compared tostandard tires. Be sure to use snow tires or tire chains on snowy and/oricy roads and drive carefully at a speed appropriate for road and weatherconditions.

Maintenance and care
■Maximum load of tire Check that the maximum load of the replacement tire is greater than 1/2of the Gross Axle Weight Ratings (GAWR) of either the front axle or therear axle, whichever is greater.
■Tire types ●Summer tires
Summer tires are high-speed performance tires best suited to highwaydriving under dry conditions. Since summer tires do not have the sametraction performance as snow tires, summer tires are inadequate fordriving on snow-covered or icy roads. For driving on snow-coveredroads or icy roads, the use of snow tires is recommended. Wheninstalling snow tires, be sure to replace all four tires.
●All season tiresAll season tires are designed to provide better traction in snow and tobe adequate for driving in most winter conditions as well as for useyear-round. All season tires, however, do not have adequate tractionperformance compared with snow tires in heavy or loose snow. Also,all season tires fall short in acceleration and handling performancecompared with summer tires in highway driving.
●Snow tiresFor driving on snow-covered roads or icy roads, we recommend usingsnow tires. If you need snow tires, select tires of the same size, con-struction and load capacity as the originally installed tires. Since yourvehicle has radial tires as original equipment, make sure your snowtires also have radial construction. Do not install studded tires withoutfirst checking local regulations for possible restrictions. Snow tiresshould be installed on all wheels. (→P. 218)
For the GAWR, see the CertificationLabel. For the maximum load of thetire, see the load limit at maximum coldtire inflation pressure mentioned on thesidewall of the tire. (→P. 481)

■ Initializing the tire pressure warning system Initialize the system with the tire inflation pressure adjusted to the speci-fied level.
■ If the tread on snow tires wears down below 0.16 in. (4 mm)The effectiveness of the tires as snow tires is lost.
■ If you press the tire pressure warning reset switch accidentallyIf initialization is performed, adjust the tire inflation pressure to the speci-fied level and initialize the tire pressure warning system again.
■When the initialization of the tire pressure warning system hasfailedInitialization can be completed in a few minutes. However, in the follow-ing cases, the settings have not been recorded and the system will notoperate properly. If repeated attempts to record tire inflation pressuresettings are unsuccessful, have the vehicle inspected by your Toyotadealer.●When operating the tire pressure warning reset switch, the tire pres-
sure warning light does not blink 3 times.●After driving for a certain period of time since the initialization has
been completed, the warning light comes on after blinking for 1minute.

CAUTION
■When inspecting or replacing tiresObserve the following precautions to prevent accidents.Failure to do so may cause damage to parts of the drive train as well asdangerous handling characteristics, which may lead to an accidentresulting in death or serious injury.●Do not mix tires of different makes, models or tread patterns.
Also, do not mix tires of remarkably different treadwear.●Do not use tire sizes other than those recommended by Toyota.●Do not mix differently constructed tires (radial, bias-belted or bias-ply
tires).●Do not mix summer, all season and snow tires.●Do not use tires that have been used on another vehicle.
Do not use tires if you do not know how they were used previously. ■When initializing the tire pressure warning system
Do not operate the tire pressure warning reset switch without first adjust-ing the tire inflation pressure to the specified level. Otherwise, the tirepressure warning light may not come on even if the tire inflation pressureis low, or it may come on when the tire inflation pressure is actually nor-mal.

4-3. Do-it-yourself maintenance
NOTICE
■Repairing or replacing tires, wheels, tire pressure warning valves,transmitters and tire valve caps●When removing or fitting the wheels, tires or the tire pressure warning
valves and transmitters, contact your Toyota dealer as the tire pres-sure warning valves and transmitters may be damaged if not handledcorrectly.
●When replacing tire valve caps, do not use tire valve caps other thanthose specified. The cap may become stuck.
■To avoid damage to the tire pressure warning valves and transmit-tersWhen a tire is repaired with liquid sealants, the tire pressure warningvalve and transmitter may not operate properly. If a liquid sealant isused, contact your Toyota dealer or other qualified service shop as soonas possible. Make sure to replace the tire pressure warning valve andtransmitter when replacing the tire. (→P. 368)
■Driving on rough roadsTake particular care when driving on roads with loose surfaces or pot-holes.These conditions may cause losses in tire inflation pressure, reducingthe cushioning ability of the tires. In addition, driving on rough roads maycause damage to the tires themselves, as well as the vehicle’s wheelsand body.
■Low profile tires (vehicles with 18-inch tires)Low profile tires may cause greater damage than usual to the tire wheelwhen sustaining impact from the road surface. Therefore, pay attentionto the following:●Be sure to use proper tire inflation pressure. If tires are under-inflated,
they may be damaged more severely.●Avoid potholes, uneven pavement, curbs and other road hazards. Fail-
ure to do so may lead to severe tire and wheel damage.■ If tire inflation pressure of each tire becomes low while driving
Do not continue driving, or your tires and/or wheels may be ruined.

■Effects of incorrect tire inflation pressureDriving with incorrect tire inflation pressure may result in the following:●Reduced fuel efficiency●Reduced driving comfort and tire life●Reduced safety●Damage to the drive trainIf a tire needs frequent inflating, have it checked by your Toyota dealer.
■ Instructions for checking tire inflation pressureWhen checking tire inflation pressure, observe the following:●Check only when the tires are cold.
If your vehicle has been parked for at least 3 hours or has not beendriven for more than 1 mile or 1.5 km, you will get an accurate coldtire inflation pressure reading.
●Always use a tire pressure gauge.The appearance of the tire can be misleading. In addition, tire infla-tion pressure that is even just a few pounds off can affect ride qualityand handling.
●Do not reduce tire inflation pressure after driving. It is normal for tireinflation pressure to be higher after driving.
●Never exceed the vehicle capacity weight.Passengers and luggage weight should be placed so that the vehicleis balanced.
377
4-3. Do-it-yourself maintenance
CAUTION
■Proper inflation is critical to save tire performanceKeep your tires properly inflated. Otherwise, the following conditionsmay occur and result in an accident causing death or serious injury:●Excessive wear●Uneven wear●Poor handling●Possibility of blowouts resulting from overheated tires●Poor sealing of the tire bead●Wheel deformation and/or tire separation●A greater possibility of tire damage from road hazards
NOTICE
■When inspecting and adjusting tire inflation pressureBe sure to put the tire valve caps back on.Without the valve caps, dirt or moisture could get into the valve andcause air leakage, which could result in an accident. If the caps are lost,replace them as soon as possible.

Wheels
If a wheel is bent, cracked or heavily corroded, it should bereplaced. Otherwise, the tire may separate from the wheel orcause a loss of handling control.
■ Wheel selectionWhen replacing wheels, care should be taken to ensure thatthey are equivalent to those removed in load capacity, diameter,rim width, and inset*.Replacement wheels are available at your Toyota dealer.
*: Conventionally referred to as “offset”.
Toyota does not recommend using the following:
● Wheels of different sizes or types
● Used wheels
● Bent wheels that have been straightened
■ Aluminum wheel precautions (if equipped)● Use only Toyota wheel nuts and wrenches designed for use
with your aluminum wheels.
● When rotating, repairing or changing your tires, check that thewheel nuts are still tight after driving 1000 miles (1600 km).
● Be careful not to damage the aluminum wheels when usingtire chains.
● Use only Toyota genuine balance weights or equivalent anduse a plastic or rubber hammer when balancing your wheels.
379
4-3. Do-it-yourself maintenance
■When replacing wheels (vehicles with a tire pressure warning sys-tem)The wheels of your vehicle are equipped with tire pressure warningvalves and transmitters that allow the tire pressure warning system toprovide advance warning in the event of a loss in tire inflation pressure.Whenever wheels are replaced, tire pressure warning valves and trans-mitters must be installed. (→P. 368)
CAUTION
■When replacing wheels●Do not use wheels that are a different size from those recommended in
the Owner’s Manual, as this may result in loss of handling control.●Never use an inner tube in a leaking wheel which is designed for a
tubeless tire. Doing so may result in an accident, causing death or seri-ous injury.
■When installing the wheel nuts
●Never use oil or grease on the wheel bolts or wheel nuts.Oil and grease may cause the wheel nuts to be excessively tightened,leading to bolt or disc wheel damage. In addition, the oil or grease cancause the wheel nuts to loosen and the wheel may fall off, causing anaccident and resulting in death or serious injury. Remove any oil orgrease from the wheel bolts or wheel nuts.
